Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To simply and certainly check the quality of a work. SOLUTION: An array sensor is used in an ultrasonic sensor. At the time of inspection, the surface of a work and the ultrasonic sensor 14 are allowed to approach as closely as possible. The position of the focus of an ultrasonic pulse is moved from the shallow layer of the work to the deep part thereof. Therefore, the attenuation quantity of the ultrasonic pulse is always minimized and a detected reflected wave can be stabilized in a high level. The number of peak signals of a waveform of the obtained reflected wave is counted at every unit time to be recorded. Further, the number of peak signals counted at every unit time is totalized. From the distribution pattern to a propagation time, the characteristics of the distribution pattern showing where depth of the work many peak signals are generated or the number of peak signals increases.  From these characteristics, the state of the internal structure in the work can be known.

IPC: H01H3/14
Filed: 1993-10-21
Abstract: PURPOSE:To provide a durable switch by which pressing operation can be performed smoothly and lightly even in any stepping-down position of a cover by seesaw operation. CONSTITUTION:When an almost center position of a regenerating cover 3 is pressed vertically in the arrow D direction, guide bars 11a and 11b of the cover 3 move slidingly vertically in holes 25a and 25b of an upper face plate 2c of a stand 2, and a (mu) switch 9 is turned on. When an arrow C position is stepped down, though the guide bars 11a and 11b are inserted into their slant posture, unreasonable force is not applied to the guide bars because of a diametrical difference. Locking points of machine screws 22a and 22b of a U-shaped metal fitting 26 are pressed, and a bridging part is opposed to a bottom surface of the upper face plate 2c, and a pressing member 17 turns on the switch 9 by performing seesaw operation. It is the same when an arrow F position is stepped down.

IPC: H01H13/52
Filed: 1994-10-27
Abstract: PURPOSE: To reliably perform the ON or OFF operation of a push-button switch by canceling the angular moment of a key top even if an external force is eccentrically applied through a process of supporting the key top by an elastic body arranged apart from a pressing part. CONSTITUTION: When an external force is applied to a part not existing on a line for linking a pressing part 2 of a key top 1 to a push-button switch 7, for example, to an attaching leg 9 part, the key top 1 is rotated, and an attaching guide 12 of an elastic body is made flex. The drag is gradually increased, and the rotation in the reversal direction is applied to the key top 1 by taking the part where the drag balances with the external force as the boundary. The pressing part 2 pushed a button 8, and the ON or OFF operation of the switch 7 can be normally performed. Since the key top 1 is operated so as to push the button 8 even if the external-force is applied on any parts of the key top 1, the size of the base plate 6, the switch 7, and the key top 1 and the design of the arranging position can be easily performed.

Filed: 1994-10-03
Abstract: PURPOSE: To obtain a display net characterized by excellent air permeability, small resistance of wind, long life of the display net, the small load acting on an object to be mounted and excellent visibility by forming a base material to a net form and forming a display part of flocking piles. CONSTITUTION: The main body part of this flocked display net 1 is composed of the net-form base material 4 and the display part 5 formed with prescribed displays (for example, 'BEWARE OF ELECTRIC WIRE') thereon. The display part 5 is formed by electrostatically flocking direct piles on the net-form base material 4 via an adhesive layer. The electrostatic flocking is applied over approximately the entire circumference of the strands of the netform base material 4, by which the spacings among the strands are assured in the flocked state. The electrostatic flocking is applied only on the required parts, by which display characters are directly formed on the base material 1. The direct piles are electrostatically flocked via the adhesive layer on the net-form base material 4 in such a manner, by which the prescribed display part 5 is formed.  Since there is no need for sticking the sheet-like material for the purpose of forming the display part unlike heretofore, the light over the entire part of the display net 1 is reduced and the handling and mounting are facilitated.

Title: Electron beam piercing method
Inventor: HORIO KENICHIRO
IPC: B23K15/08
Filed: 1985-11-27
Abstract: PURPOSE:To reduce a waiting time and the cost by moving a beam by repeating in order the process of irradiating one beam pulse on the work point and by irradiating the necessary number of pulses on the whole work points. CONSTITUTION:The body 7 to be worked on an X-Y table 6 is parted into plural work blocks 17.... A piece of pulse is then irradiated on a work point 21 by locating an electron beam 8 at the block center position 10 first, then by deflecting the beam. Then one piece of the pulse is irradiated on the work point 23 as well by deflecting the beam and this is repeated in order. The necessary number of pulses is irradiated on the whole work points by returning to the work point 21 again after reaching to the final work point 25. After the block 17 being completed it is moved to the block 17'. The need of taking the waiting time 100 times the pulse width in the case of fixing the beam is therefore eliminated and the cost can be reduced by reducing the waiting time.
